Audio problem: When Tim and Alvey are chased down the alley by Loki, Loki pulls out a huge fire ball, and then Odin the great god takes over Tim. After Odin the great god says, "I've had it up to here with you!", you can see Alvey in Tim's arms crying, but you can't hear Alvey crying.

Continuity: During the scene where the baby is peeing on Tim, in one shot his hair is wet, in the next it's dry and in the next shot it goes back to wet again.

Continuity: When Loki arrives at the Avery's home to check out Alvey, his car skids to a stop pinning a squeeze toy under the front right tire. When he leaves following Tim and Alvey into the city, the squeeze toy is not under the tire.

Continuity: When Otis (the dog) is in the trap, in the shot before he falls in the piano, Tim is standing in the room, but when the piano closes, he is not there. He suddenly appears in the next shot, so he couldn't have run out of the room and come back in.
